I WILL POST THE ANSWERS TO THE PRACTICE QUIZ AT APPROXIMATELY 8PM!

Objectives tested on the quiz:

  • Classify matter as a pure substance (element or compound) or mixture (homogenous or heterogeneous)
  • Compare and contrast chemical and physical properties
  • Compare and contrast chemical and physical changes
  • Define and identify states of matter and draw particle diagrams describing states of matter

Your Periodic Table Unit Test is this Wednesday, December 18. The following material will be on your test:

Standards:

  • Explain how properties of elements and the location of elements on the periodic table are related.
  • Explain how elements are arranged within the periodic table (valence electrons, atomic size, electronegativity, ionization energy)

Vocabulary:

  • Metal
  • Nonmetal
  • Metalloid
  • Alkali metal
  • Alkaline earth metal
  • Transition metal
  • Halogen
  • Noble gas
  • Conductivity
  • Malleable
  • Ductile
  • Brittle
  • Melting point
  • Physical property
  • Valence electron
  • Lewis dot diagram
  • Atomic radius
  • Electronegativity
  • Ionization energy
  • Shielding electron
  • Effective nuclear charge

NEED TO KNOW:

  • Properties of metals, nonmetals, and metalloids
  • Properties of the 5 periodic families
  • Valence electrons, charge, and Lewis dot diagrams for elements in groups 1-2 and 13-18
  • Whether atoms will gain or lose electrons depending on their valence electrons
  • Explain why each periodic trend occurs in words and draw the trend on a periodic table
  • Put elements in order based on their atomic radius, electronegativity, or ionization energy
  • Calculate the number of shielding electrons and effective nuclear charge of an atom
  • Be able to answer the following questions:
    • How are properties of elements and the location of elements on the periodic table related? Use at least 3 examples of properties to support your claim.
    • Why do atomic radius, electronegativity, and ionization energy increase/decrease down a group?
    • Why do atomic radius, electronegativity, and ionization energy increase/decrease across a period?
